I am looking to migrate my father's pop3 email account from comcast.net to a new account I created for him on my fusemail service. Does anyone know of an easy way to transfer email via pop3 with folder structure to this new service?

He is using the webmail interface at comcast and is sticking with Pop3. Right now, my major problem is that he has folders containing email and I see no way to do a manual export of all email (ala Outlook's PST Export).

The hurdle is that POP3 doesn't natively support uploading email to the server.

I'm thinking you might want to use Thunderbird to make the transfer if IMAP is available. You could download everything locally, then connect via IMAP to the new account and upload the email via Thunderbird. Then from there on just use the webmail client and POP3.

I'm fairly confident that will work smoothly, but always test with a few emails first before you try to do the whole thing.

In that case, all that I can come up with is forwarding, or as Tinjaw advised, set it up as IMAP at first. Then after all are on the server see if you can convert to POP. The folks at Fusemail may also be able to assist you with this. I use Fastmail and I can ask the dev's for this kind of help - sometimes thay can, sometimes not. I have heard that Fusemail has relatively "friendly" developers. Can't hurt to write them and see if they can help.

Does he have a lot of saved messages? Forwarding them as attachments would be the best way, but that could be done more easily if you can download them first, maybe into Outlook Express.
